Description

The The present invention relates to a winding device for covering of wall openings or windows with the features of the claim 1.

Out The prior art are already up and up in the vertical direction developable winding devices known. Such winding devices come For example, for the variable shielding of rooms, the variable Ventilation and / or foreclosure of animal houses, of greenhouses or the like for use. Usually Such winding devices have flexibly configured fabrics Cover on. Next are from the prior art winding spools known, on which the flexible fabric can be wound up.

Such a winding device is for example in the DE 201 17 865 U1 disclosed. There, a flexible fabric can be wound on a shaft that is driven by a motor. During winding, the shaft rotatable about a horizontal axis moves upward in a vertical direction. Further, the flexible fabric is fixed at its upper end with ropes on a second shaft. This serves to define a fixed gap opening between the second shaft and the tissue. In this known winding device, the fabric must carry the weight of the shaft when winding. This leads to a tensile stress of the tissue. Due to the stress, the tissue can be damaged under unfavorable circumstances. Furthermore, during winding, the diameter of the shaft increases with the fabric gradually wound thereon. At a constant rotational speed of the rotating shaft, this results in an accelerated movement of the shaft with tissue during the winding process.

In order to compensate for the increasing diameter between wave and tissue during the winding process and the associated increase in speed, various efforts will be made over the course of time. For example, the DE 202 14 076 U1 a device for shielding a room with an upper and a lower roll system. The difference in diameter between the upper and lower Wickelement is compensated by Aufspannmittel. In practice, winding devices in which additional elements, such as clamping means, can be dispensed with to compensate for the increasing diameter, are desirable.

task The invention is a simple as possible, cost-effective and universally applicable winding device for covering wall openings or to provide windows where tissue is unwound and unwound becomes.

The The above object is achieved by the device, which the features of claim 1 comprises.

The winding device according to the invention includes a roll-up cover, a wave-like trained or also formed only by a lower seam or a lower fabric edge Deflection element and a lifting and lowering device. The cover element also has an upper, arranged parallel to the deflecting element Long edge on. The lower longitudinal edge is either connected to the deflecting element or formed by this, so that by a rotation of the deflecting element or the lower fabric edge The covering element can be rolled up or unrolled about a horizontal axis is. The lifting and lowering device comprises at least one rope, connected to the upper longitudinal edge of the cover is. This raises and lowers the upper fabric edge analog the rope movement. Since the deflection arranged at the lowest point and is guided in a rope bend and hangs, The lower edge of the fabric or the deflecting element is rolled up the rope in rotation and rolls the tissue or the curtain doing it automatically.

The at least one rope is at least approximate parallel or V-shaped in two relatively opposite Directed directions of movement and leads simultaneously the deflecting element or the lower fabric edge and thus the itself up or rolling cover. The inventive Winding device for covering wall openings or windows For example, in stables or greenhouses applied and used meaningfully. The roll-up cover For example, by a fabric or interconnected plastic slats o. The like. Be formed.

The wavy deflecting element could optionally guide grooves or radial depressions o. The like. For initial guidance of the cables have. Since the rolled-up covering element envelops the deflection element or the seam of the cover element after just a short revolution, the cable no longer touches these grooves or radial depressions, so that they are dispensable and can optionally be dispensed with. With regard to its length and its diameter, a large number of possible variations is provided for the deflecting element. The desired width of the opening to be covered defines the width of the cover element and thus the length of the deflection element. By parallel and spaced arrangement of several ropes side by side over the entire width of the cover easily widths of several meters can be covered, without causing a slack or a deflection of the deflection comes. Such a deflection is not to be feared anyway, since the lower edge of the fabric can be made very easily. It is not connected to a shaft and does not have any load-bearing properties, so that a stable and thus heavy construction is not required.

The Lifting and lowering device according to the invention comprises at least one rope, with which the upper longitudinal edge of the cover connected is. The rope is in two opposite to each other Movement directions led. The term rope must be in Context in terms of its conceptual definition broadly interpreted be, as for the rope, for example, also chain-like Structure or other deflectable elongated fasteners can be chosen. Also ribbons, stripes or even wider tissue sections can do this are used and should therefore be based on the chosen term be included with the rope.

The Deflection element is characterized by at least one rope, which at least approximately parallel in two mutually opposite directions of movement or optionally also guided in a V-shaped arrangement is, carried, held and rotated and the tissue or the curtain while up and unrolled. Optionally, you can the ropes also run diagonally, without any impairment the function or other limitation of the invention connected is. So the ropes can be at an advantageous Alternative of the invention optionally be arranged in V-shape, which For example, advantages in terms of the ropes to be wound or the space required can have this. The variant to choose in the first place according to the installation and space conditions and possibly after the preferred winding ratio.

at a winding of the rope is a relative movement of the two parallel sections, allowing the winding of the winding element and thus the winding and unwinding of the cover is effected. In this case, the relative movement of the deflecting element or the lower Fabric edge by an opposite movement of both sides of the Ropes generated.

The Cover elements have an upper and a lower, parallel to the Deflection arranged or forming the deflecting longitudinal edge on. The longitudinal edges can stabilize additionally be provided with reinforcements.

As already mentioned several times, is the lower longitudinal edge the cover member connected to the deflection or forms even the deflecting element, so that by a rotation of the deflecting element or the lower longitudinal edge about a horizontal axis of rotation the cover can be rolled up on the deflection element. The horizontal arranged axis runs through the deflecting element. The connection between deflector (if present) and lower Longitudinal edge of the cover can numerous design variations subject. For example, the connection by rivet screw or adhesive bonds.

at a further preferred embodiment, the at least one rope arranged at its free ends on a shaft become. If the shaft is now placed in a rotating motion, so in a first step, the rope and thus the cover drained while rolled up the cover on the deflector. If the cover is completely rolled up, it takes place in a second step, the movement of the deflecting element in vertical Direction upwards. Regarding the number of ropes used Within the scope of the invention, the user has no limits. For example, with longer cover elements several ropes are used.

When advantageous in the winding device according to the invention has the synchronous speed of the winding speed with exposed to the Auflass- and lifting speed of the tissue. The winding speed depends on the reeling speed the ropes, which are used for winding the cover and for generating whose winding and unwinding rotation are necessary.

The Rotational movement of the shaft can be optionally by manual operation be generated. Here, for example, a crank on the shaft be arranged, by which the user the rotation of the shaft can cause.

Further Embodiments are provided in which the rotation is generated by a drive unit. The drive unit can a motor, for example an electric motor.

Also are manual and not manual variants of the claimed invention in which the lifting and Lowering device is designed as a cable. In this embodiment There may be guide rollers that support the For example, rope from its vertical direction of movement in one deflect horizontal direction of movement.

In the context of the invention, it is optionally possible to provide a plurality of cables with different functions. For example, at least one first cable and at least one second cable can be provided. The second rope may be provided for lifting and lowering the upper longitudinal edge, while the first rope for winding and for Lifting and lowering of the deflecting element is provided. This makes it possible to design both processes independently of each other. Also, the ropes can be configured in terms of power optimized in terms of number, material and diameter.

The second rope can, for example, with its first free end the shaft can be arranged and with its second free end the upper longitudinal edge of the cover. The first rope can be arranged for example with two free ends on the shaft.

moreover embodiments are conceivable in which the first rope is arranged with a free end on the shaft and with his second free end at the upper longitudinal edge of the cover. Further, in this embodiment, the second rope with a free end is arranged on the shaft and with its second free end at the upper longitudinal edge of the cover.

It I would like to emphasize again at this point that with the deflector not necessarily a rigid part or at all a separate part of the winding device according to the invention must be meant. The deflection can, for example, by the lower Tissue space or be formed by the lower edge of the fabric, the / the to be defined by the articulation of the windable ropes with these Direction and in a loose winding turns while winding or unwinding.

Especially advantageous to the winding device according to the invention is their very safe handling, since the forces acting are significantly lower than in the previously known winding devices. For example, one would accidentally enter the winding device retracted hand lead to no injury, as the Ropes would slip through and the fabric would not would be wound up further. In known systems must a much higher winding force introduced into the winding shaft be because this force is introduced only at one axial end can and otherwise the fabric is not on a length can be wound up to 80 m or more. On the other hand the winding force in the winding device according to the invention on the entire width of the fabric or the curtain initiated.

in the Below are embodiments of the invention and their advantages with reference to the accompanying figures closer explain. Other features, objectives and advantages of the present The invention will become apparent from the following detailed description of a preferred Embodiment of the invention, as a non-limiting Example and reference to the accompanying drawings takes.

The 1a to 1d show schematically the operation of an embodiment of the claimed winding device.

1a shows a winding device 1 of the claimed type. Shown are a side view A and a front view B. The winding device 1 includes a cover 3 with an upper longitudinal edge 5 and a lower longitudinal edge 7 , The cover element 3 is formed with respect to its length such that it is not on the deflecting element 9 rolled up the wall opening 11 partially or optionally completely cover. The long edges 5 and 7 of the cover 3 may have additional reinforcements. The lower longitudinal edge 7 is fixed to the deflecting element 9 connected. The deflecting element 9 hangs between the rope sections 13 and 13 ' and becomes in the rope bend of the oppositely moving sections 13 and 13 ' rolled up or rolled up. At the lower deflection of the cable sections a bend is formed so that the rope 13 the rotational movement of the deflecting element 9 causes. The rope 13 respectively. 13 ' is guided parallel to a vertical axis Z. The direction of movement of the rope 13 while the downhill is in 1a indicated by the arrow Y direction. The rope 13 respectively. 13 ' is at the junction 17 with the upper longitudinal edge 5 of the cover 3 connected.

The 1b to 1c show successively the process of transfer of the winding device 1 from the in 1a shown open position corresponding to a basic position 1c ,

In 1b is the winding device 1 only partially open. The cover element 3 is already partially on the deflection 9 rolled up. The wall opening 11 is in 1b only in the lower area of the cover 3 covered. The upper longitudinal edge 5 is parallel to a horizontal axis (not shown) in the in 1a guided by the arrow Y direction indicated movement.

The rotational speed of the deflecting element 9 remains during the movement of the upper longitudinal edge 5 in the in 1a direction of movement indicated by the arrow Y is not necessarily constant, but is possibly due to the increasing diameter of the deflection element 9 with the covering element wound thereon 3 slower.

The inventive design is an automatic adjustment of the rotational speed of the deflecting element 9 to the diameter of the deflecting element 9 with cover element 3 even if it changes due to dirt, wrinkles or cold.

1c shows the cover 3 in the fully rolled up state on the deflection 9 , The wall opening 11 is completely exposed. Starting from this condition, the directions of movement of the ropes can 13 and 13 ' now be guided against the previous direction of movement, whereby the open state of the winding device 1 , as in 1a shown, can be restored. To the winding device of the in 1c shown basic position in the in 1d To transfer shown position, the direction of movement of the ropes is not maintained, but the draining rope is the lifting rope. As a result, the deflecting element is raised with the cover in the rolled up state. It is conceivable that the transfer to the in 1d shown position can also be done from another position of the winding device, for example. From a half-opened position accordingly 1b ,

Out 2a the structure of the embodiment will be apparent. The free ends 23 and 25 of the rope 13 respectively. 13 ' are on a wave 19 arranged. The shaft is powered by a motor 21 set in rotation. Both free ends 23 and 25 are stuck with the wave 19 connected. In the area of the first free end 23 is residual rope 27 on the shaft 19 arranged so that by unwinding the residual rope 27 from the wave 19 a downward movement of the rope 13 can be brought about.

Analogous to the 1a to 1c done as in 2 B to 2c shown, a rolling up of the cover 3 on the deflecting element 9 ,

In 2 B is the winding device 1 only partially open. The wave 19 is in the rotating state, leaving the residual rope 27 from the area of the first free end 23 is handled by the deflection 9 is continued and then in the area of the second free end 25 is arranged. The direction of rotation of the shaft 19 can by the engine 21 be changed so that the rest rope 27 again in the area of the first free end 23 can be arranged. With unwinding the remaining rope 27 goes a movement of the upper longitudinal edge 5 in the in 1a indicated arrow Y direction, whereby the cover 3 on the deflecting element 9 being rolled up.

By fixing the rope 13 respectively. 13 ' at the shaft is omitted from the in 2c state shown another deflection of the rope 13 , because the rope is completely unrolled at this moment and now not further lowered by the further rotation of the shaft, but is rolled up. This raises the rolled-up cover 3 up when the two ropes 13 and 13 ' be raised.

The 2e schematically shows the operation of another embodiment of the claimed winding device 1 with wave 19 , The free ends 23 and 25 of the rope 13 respectively. 13 ' are on a wave 19 arranged. The shaft is powered by a motor 21 set in rotation. Both free ends 23 and 25 are stuck with the wave 19 connected. In the area of the first free end 23 is residual rope 27 on the shaft 19 arranged so that by unwinding the residual rope 27 from the wave 19 a downward movement of the rope 13 can be brought about. Analogous to the 1a to 1c done as in 2 B to 2c shown, a rolling up of the cover 3 on the deflecting element 9 ,

The ropes 13 respectively. 13 ' are in this variant V-shaped arranged, which makes it clear that the ropes by no means necessarily have to run in a useful and expedient parallel arrangement, but may well have a different course.

The 3a to 3d show schematically the operation of another embodiment of the claimed winding device 1 with cable.

The winding and unwinding of the cover 3 on the deflecting element 9 and the lifting and lowering of the deflecting element 9 are controlled via cable in the embodiment shown. The cable comprises several pulleys 27 , The rope 13 , respectively. 13 ' are guided over the pulleys. In the embodiment shown, that part of the rope 13 , which performs the downward movement, by 270 °, through the left of the two pulleys 27 , turned counterclockwise and continued.

The part of the rope 13 ' which performs the upward movement is also in the embodiment by the left of the two pulleys 27 continued. However, the continuation takes place in the opposite direction to the continuation of the rope 13 , By the right pulley, the change from the discharging rope to the lifting rope is effected, which for the change of the 3c in the 3d is required.

With regard to the embodiment with cable, numerous variations are conceivable in practice, with respect to the number and position of the pulleys used 27 can vary. The operation of the cable can be done manually, but also by a motor.
